    A Fibre Optic Long Period Grating Immunosensor for Campylobacter jejuni with Enhanced Sensitivity by Bacterial Staining
    (Cranfield University, 2018-10-22 10:29) Rendon Romero, Antonio
    Poster presented at the Cranfield Doctoral Network Annual Event 2018. Campylobacteriosis is one of the most widely reported bacterial cause of gastroenteritis in humans in the world. One of the bacterial species that most causes the disease is Campylobacter jejuni. The detection of Campylobacter jejuni by sensitising the surface of an optical fibre long period grating (LPG) with covalently attached rabbit polyclonal antibody is explored. The sensitivity of the sensor is enhanced by bacterial staining allowing the detection of concentration as low as 102CFU/mL. Finally, the selectivity of the sensor against other bacterial species is evaluated.

    A numerical study of deep borehole heat exchangers in unconventional geothermal systems
    (Cranfield University, 2018-10-22 10:16) Renaud, Théo
    Poster presented at the Cranfield Doctoral Network Annual Event 2018.The geothermal energy sector is facing numerous challenges related to heat recovery efficiency and economic feasibility. Ongoing research on superheated/supercritical geothermal system, potentially representing a intensive amount of energy, is developed in Europe notably the Iceland Deep Drilling project (IDDP). The well IDDP-1, which reached a magma intrusion at a depth of 2100 m, raised new opportunities to untap the geothermal potential near shallow magmatic intrusions. Given their highly corrosive nature, geothermal fluids weaken the wellbore’s integrity during conventional geothermal production. Deep Borehole Heat Exchangers (DBHE) that do not require fluid exchange between the surface and the wells represent a strategic alternative to recovering heat from these unconventional geothermal resources, while minimising the risk of in-situ reservoir damage. The thermal influence and heat recovery associated with a hypothetical DBHE drilled into the IDDP geological settings were investigated via Computational Fluid Dynamics (CFD) techniques until 10 years of production, when the system reaches full equilibrium. Two wellbore designs were simulated, based on simplified geological properties from the IDDP-1 well description. The results show that, during the first year of production, the output temperature is function of the working fluid velocity before reaching pseudo-steady state behaviour. The cooling perturbation near the bottom hole is shown to grow radially from 10 to 40 m between 1 and 10 years of production, and the output thermal power calculated after 10 years reaches 1.2 MW for a single well.

    Conceptualising Supply Chain Management: An Objective-Oriented Approach
    (Cranfield University, 2018-10-22 10:14) Alkebaisi, Hussain
    Poster presented at the Cranfield Doctoral Network Annual Event 2018.Although it has been more than three decades since the concept of Supply Chain Management (SCM) was first introduced, there are still significant attempts at, and a call for conceptualising, defining, remodelling and identifying the theory(s) behind it. There is no consensus in the literature on a concise and precise definition of SCM nor its underpinning theory(s). A rigorous theoretical framework has not yet been developed; the existing models like Supply Chain Operations Reference (SCOR) and the Global Supply Chain Forum (GSCF) models lack the details called for in a holistic model that encompasses the essence of SCM and integrates the best features of the existing models and covers their shortcomings.The argument in the literature is that: “research and practice would be improved if a single definition were adopted” (Mentzer et al., 2001); “closing the gap between SCM theory and actual practice would be the development of a single, unifying SCM framework that both incorporates the best aspects of the existing, widely used frameworks and addresses their current limitations” (Moberg et al., 2008). However, in this research, the author argues that a consensus on a unified conceptual/theoretical framework of SCM will contribute to solving those theoretical issues.The literature has shown that most of the research approaches which were used to solve those theoretical issues were process-oriented or business functions-oriented, that is, the focus was on what firms and organisations are doing, where they do it, or how they do it. However, the main gap the researcher has identified through the study and the analysis of the literature is that an Objective-Oriented approach has not been investigated in resolving those theoretical issues. Also, the researcher found that the objectives of SCM and supply management as a whole were scattered in the literature. In this study, the researcher objective is to investigate the viability of using this approach in solving those theoretical issues.The researcher found that an appropriate research methodology to investigate the viability of an Objective-Oriented approach would be to apply the Grounded Theory research methodology, which is a well known qualitative research methodology that is used in developing theories or theoretical frameworks from data (grounded) through line-by-line coding and categorising process. Recent work reported by Randall and Mello, (2012) recommended the use of the Grounded Theory research methodology as they established that grounded theory “can be an appropriate tool for creating theory in supply chain research”. This methodology has also been recommended by Denk, Kaufmann and Carter, (2012) and Manuj and Pohlen, (2012)Therefore, this research focuses on the implementation of the Grounded Theory research methodology through an Objective-Oriented coding system that will analyse multiple data resources including the literature, websites, recorded lectures and recorded interviews. Through this approach, the researcher was able to: conceptualise SCM, identify the theory behind it, define the concept precisely and concisely and develop a unified model that visualises SCM.

    Control for Motion Sickness Minimisation in Autonomous Vehicles
    (Cranfield University, 2018-10-22 10:13) Htike, Zaw
    Poster presented at the Cranfield Doctoral Network Annual Event 2018. Autonomous vehicles or self-driving vehicles are expected to become a wide scale deployment for public use in the very near future. Recent study shown that there will be increase in frequency and severity of motion sickness due to engaging in non-driving tasks. This establishes motion sickness as being the elephant in the room and the increase in occurrence of motion sickness is predicting to be a limitation to the successful introduction of full vehicle automation. Motion sickness is a condition marked by symptoms of nausea dizziness, and other physical discomfort. The accepted cause of motion sickness is being the sensory conflict between inputs from the visual, vestibular and somatosensory systems of human body. Factors that might increase or decrease the severity of sickness symptoms includes ages, genders, alcohols, drugs, motion environments, other environmental and psychological aspect. Nevertheless, motion sickness in road vehicles is most closely related to low-frequency fore-and-aft, lateral, yaw acceleration. The range of these frequencies stated in the Standards guideline (International Standard, British Standards and Military Standards) for human exposed to whole-body mechanical vibration and shock, are in the range between 0.1 to 0.5 Hz. Previous experiments studies also shown that passenger motion sickness increases with increased exposure to lateral motion at low frequencies less than 0.5 Hz. This project aims to develop a control strategy that could minimise motion sickness in autonomous vehicles. The first part of the project explores the empirical formulations outlined in the Standards to evaluate motion sickness as a form of predicted illness rating or motion sickness incidence. A simple optimisation algorithm is developed to investigate the effectiveness of reducing motion sickness based from such formulations. The second part of the project looks at the sensory conflict theory for estimating motion sickness by adopting the existing 6-DOF subjective vertical conflict model. This model would later incorporate with vehicle model, and an optimal control strategy would be implemented to minimise motion sickness.

    Maximizing the value of trade wastes
    (Cranfield University, 2018-10-22 10:35) Berzal de frutos, Olivia
    Poster presented at the Cranfield Doctoral Network Annual Event 2018.Anaerobic digestion (AD) is the use of microorganism in the absence of oxygen to degrade organic compounds. AD is commonly used to treat highly concentrated wastes, such as waste sludge from municipal wastewater treatment plants. Similar, trade wastes (TWs), wastewaters generated from industrial or production processes, known to contain high levels of organics as compared to domestic wastewater, are often treated in anaerobic systems. The treatment of sludge in AD has been seen to be enhanced with the addition of TWs. However, as any biological system, the bacteria may be affected by toxic compounds present in the substrate, and TWs are a potential source of compounds affecting anaerobic bacteria with, for instance, ammonia, heavy metals, and fats oils and greases. Therefore, there is a need to understand the possible impact of those compounds in AD of TWs and sludge. This research aims to understand the limitations and benefits of using TWs in anaerobic digesters treating wastewater sludge and in particular the impact TWs may have on biogas production and stability of the reactors. The impacts of using TWs on the AD of sludge were assessed in this project by testing controlled addition of the compounds of interest in batch reactors treating sludge. This data will be compared to the characteristics of TWs to select them for further experiments. The final result will be a decision support tool that could be used for water companies to decide the TWs to be added to the digester.

    Poster: A Fresh Look at Optical Interferometry
    (Cranfield University, 2016-08-17 10:36) Kissinger, Thomas
    Poster presented by Thomas Kissinger at Set for Britain 2016 event in the UK parliament on 07.03.2016. Abstract: Optical interferometry is a widely used technique for ultra-precision distance measurements in many areas of science and technology, enabling fundamental physical experiments, such as the hunt for gravitational waves, and underpinning important industrial technologies, such as semiconductor fabrication. My particular research deals with the question on how multiple measurements at different points can be taken simultaneously using only one instrument. This can be achieved by appropriately modulating the optical wavelength of the laser used and a very simple way to perform these measurements is the signal processing technique developed during my PhD thesis project. A key advantage of this approach is that it reduces the number of optical components needed and instead shifts complexity of the measurements into the electronics, potentially enabling very cost-effective measurements. As this technology is very new many potential applications still remain unexplored.

    Power Gearbox and Pitch Control Mechanism for Open Rotors - Investigation of Preliminary Design Methodologies
    (Cranfield University, 2018-10-18 10:00) guiomar San benito pastor, Diana
    Poster presented at the Cranfield Doctoral Network Annual Event, September 2018.The expected result of this PhD research is a design methodology that would allow establishing the feasibility of a pusher counter-rotating open rotor (CROR) engine architecture, taking into account both performance and mechanical integrity aspects. The analysis will consider the preliminary design of the main technology enablers, i.e. the advanced power gearbox (PGB) and the pitch change mechanism (PCM), delving into sizing, mechanical integrity aspects and optimal positioning of the components within the propulsion system. The study will then be extended to assess: Design for performance through simulated flight trajectory assessments over selected missions; Lifing aspects of the components and their implication on maintenance costs; Economic benefits through a financial viability analysis. A key requirement is to optimize these objectives by determining the minimum size of the power transmission system of the CROR engine to transmit power from the free turbine to the counter-rotating propellers. This requirement will need to be met without compromising its mechanical integrity nor the overall performance of the engine.
